I have a 1974. ( I think that's the year) nishiki road compe. Just pulled it out of my barn, I rode it while in university from 1976 to the 81. It origionally belnged to my sister who pased away in 1976', so i didnt purchase it. Been sitting ever since. I planning to ride again hurt my foot jogging and need to change my exercise mode. What size frameis right for a 5"6" inch guy with short 28" inseam. Where can I find some parts: Caps for the crank lower bracket Pedal crank Can I get the original sow up rims and tires Toe holder and straps. In the nishiki line where did this bike come in, I know it was a higher end but what ewre the better models in it's day?
